Do I need to edit my theme?

No. Plug & play is on by default. Disable it in settings if your theme already outputs custom elements and you want to avoid double processing.

Frequently Asked Questions

Common questions about Sasim WebP Auto Converter

No. The plugin creates additional .webp files alongside the originals. With plug & play enabled, browsers that support WebP receive <picture> markup automatically.

No. Plug & play is on by default. Disable it in settings if your theme already outputs custom <picture> elements and you want to avoid double processing.

With plug & play enabled, the plugin outputs <picture> with a WebP <source> when sibling files exist. Browsers that support WebP load the smaller format; others fall back to JPEG/PNG via the <img> tag.

80–85 is a good starting point for photographs. Lower values reduce file size but may reduce visual quality. Re-run batch conversion after changing quality to regenerate existing WebP files.

Yes. Use Generate WebP on the settings page to process the media library in batches.

No. All conversion happens locally using PHP GD or Imagick. The batch tool uses WordPress AJAX in the admin only.

Plugin options are removed. Generated .webp files remain on disk so your site keeps working; delete them manually if you no longer need them.

Plug & play enhances standard WordPress image output. Page builders that bypass core APIs may need theme helpers (see plugin documentation). CDNs that serve your uploads directory will serve .webp siblings when URLs point to them.

Avoid running multiple plugins that both convert uploads to WebP or rewrite the same image markup. Test on staging first.

JPEG and PNG uploads are converted. SVG and GIF are not converted. WebP output requires server support (GD imagewebp or Imagick).
